obs-build (20210120-4) unstable; urgency=medium

  * Ensure the build environment is set up correctly:
    - Wrap chroot + su in a function to consistently set up environment
      for builds.
      Since "su -" cleans the environment, we need to tell it to keep
      variables we want to preserve. To make this easier, create a new wrapper
      su_deb_chroot that runs chroot and su and sets up the environment.
